The device is characterized in that the fetal head sliding plate is in the shape of a spoon, and the front end of the spoon-shaped fetal head sliding plate is provided with a forked push head which pushes down the lower edge of a womb cut along a fetal head. The device has the beneficial effects that the novel device for delivering head in a caesarean section does not need to enter a uterine cavity, a front fork of the childbirth head device pushes down the lower edge of the womb cut along the fetal head to enable the fetal head to be positioned on a spoon of the device for delivering head, the fetal head successfully labours out of the womb by means of the push force of the belly, then the device for delivering head is lifted upwards, and the fetal head successfully labours out of the abdominal cavity. A most reasonable childbirth head path finished by two steps is realized, namely, the fetal head is firstly out of the uterine cavity and then is out of the abdominal cavity. The incidence rate of mother and infant complications, such as cut lacerated wounds and haemorrhage of the womb of a puerpera, asphyxia of a newborn baby, and the like caused by stretching the hand into the childbirth head of the uterine cavity is reduced.

Description

Device for delivering head in caesarean section

Technical field

The invention belongs to the cesarean section medical apparatus and instruments, relate in particular to a kind of device for delivering head in caesarean section.

Background technology

At present, cut open the palace product and become the most frequently used operation of obstetrics and common childbirth options.When head cesarean, a childbirth technology is the successful key of operation.A childbirth modal method is now: patient's right hand enters cavity of uterus by the lower uterine segment transverse incision, and (puerpera foot side) lifts fetal head obliquely upward, makes give birth to cavity of uterus and the abdominal cavity is disposable finishes of fetal head.People such as Jiang Shuling, Zhang Qilin " fetal head help exert oneself the application of device in cesarean section know from experience " discloses a kind of fetal head and has helped and exert oneself device, adopt fetal head to help the childbirth device to enter cavity of uterus and help the childbirth head, the fetal head of being made by rustless steel helps childbirth device structure to be: comprise handle and fetal head slide plate two parts, integral body is the natural shape the when patient gives birth to fetal head in the cesarean section, and the wrist back of the body hade degree when getting fetal head in handle and slide plate angle and the cesarean section is similar.During use, will help childbirth device slide plate portion to slip in the cavity of uterus along the fetal head leading edge by the abdominal cavity otch, the slide plate top reaches the fetal head below, and handle is vertical with the abdominal cavity transverse incision, and in horizontal direction, its effect is similar to the leverage of single leaf obstetric forceps.Ideal childbirth parting line should be a square.That is, fetal head also is vertical clinostatism to puerpera's foot side during puerpera's horizontal position; Through the lower uterine segment otch fetal head of giving birth to also should be horizontal direction.After fetal head is given birth to cavity of uterus, upwards lift fetal head again and go out the abdominal cavity.This kind given birth to a mode in two steps and seen it is the most rational from the mechanics angle.There are many irrationalities in a childbirth technology now.First childbirth parting line is unreasonable: patient's right hand (comprises that various apparatuses help childbirth) obliquely upward with fetal head and lifts fetal head in cavity of uterus, all violated normal childbirth parting line, certainly will run into the resistance of lower uterine segment cutting shoulder, increases the difficulty of childbirth head; Two to be that hands is gone into cavity of uterus childbirth unreasonable for it: cut open the palace and produce under the prerequisite of childbirth head smoothly, otch is the smaller the better.But patient's right hand enters and lifts fetal head in the uterine incision, certainly will need bigger uterine incision and abdominal cavity otch.Above-mentioned irrationality has increased the incidence rate of mother and baby's complication such as uterine incision laceration, hemorrhage and asphyxia of newborn.

Summary of the invention

The present invention is in order to overcome deficiency of the prior art, a kind of device for delivering head in caesarean section to be provided, and a childbirth device need not to enter cavity of uterus, has realized finishing in two steps the most reasonable route of childbirth head, and promptly fetal head goes out cavity of uterus earlier, goes out the abdominal cavity again.

The present invention for achieving the above object, be achieved through the following technical solutions: a kind of device for delivering head in caesarean section, comprise by handle and fetal head slide plate and constitute integral body, handle and slide plate angle exactly like the angle that patient's wrist back of the body is stretched, it is characterized in that: described fetal head slide plate is cochlear, and described cochlear fetal head nose is provided with cuts somebody's hair the uterine incision lower edge along the fork-shaped that pushes away under the fetal head.

Described fork-shaped is cut somebody's hair and is made of fetal head slide plate plate tongue that extends forward and the push pedal with the uterine incision expansion that places its below to have angle.

The described fork-shaped section configuration of cutting somebody's hair is acute angle or arc or manger shape.

Beneficial effect: novel device for delivering head in caesarean section need not enter cavity of uterus, a childbirth device front fork along pushing away under the fetal head, is on this childbirth device spoon fetal head the uterine incision lower edge, by the abdominal part thrust fetal head uterus of giving birth to smoothly, carry a childbirth device again, then the fetal head abdominal cavity of giving birth to smoothly.The most reasonable childbirth parting line that realization is finished in two steps promptly goes out cavity of uterus earlier, goes out the abdominal cavity again.Minimizing is gone into the incidence rate that cavity of uterus childbirth head causes mother and baby's complication such as puerpera's uterine incision laceration, hemorrhage and asphyxia of newborn because of hands.
